SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Visualize complex systems, flows, and state changes so readers grasp structure and behavior in seconds instead of parsing long prose or crowded diagrams.

Core Features & Use Cases

Diagram-as-code templates for Mermaid flowchart, sequence, state, ER, class, quadrant, and C4 context/container diagrams.
Decision guidance that maps questions to the right diagram type and advises when prose is better than a diagram.
Best-practice rules for readability: labeled arrows, legends, direction conventions, node limits, and repository-friendly diagrams.
Use Case: Replace a 5-paragraph RFC lifecycle with a concise state diagram or produce a C4 container view for a three-service system that renders in GitHub.

Quick Start

Ask the visual-communication skill to produce Mermaid or C4 diagram code by describing the system, the diagram type (flowchart, sequence, state, ER, C4), and any labels or branches.

FAQPage Schema

How do I generate Mermaid diagrams from textual system descriptions?▼

Generate Mermaid diagrams by providing a textual system description and specifying the diagram type, such as flowchart, sequence, or ER. The Skill outputs syntactically valid Mermaid code with labeled arrows and legends that renders directly in GitHub. You simply describe the architecture or process flow to get the diagram code.

When should I use a C4 container diagram vs a standard flowchart for architecture visualization?▼

Use a C4 container diagram for visualizing three-service system architectures and dependencies, and use a standard flowchart for process flows and decision branches. The Skill provides decision guidance mapping your specific structural questions to the appropriate diagram type for optimal system readability.

Can I produce sequence and state machine diagrams that render in GitHub repositories?▼

Yes, you can produce sequence and state machine diagrams that render in GitHub. The Skill generates repository-friendly Mermaid templates for sequence, state, and class diagrams, ensuring the syntax is valid and compatible with GitHub and similar documentation tools.

What's the best way to visualize complex system flows without drawing crowded diagrams?▼

The best way to visualize complex system flows without crowding is using diagram-as-code with enforced best-practice readability rules. The Skill applies node limits, direction conventions, and labeled arrows to replace long prose with concise state or C4 diagrams for immediate comprehension.

Do I need to specify the diagram type to get valid C4 or Mermaid code?▼

You do not strictly need to specify the diagram type, as the Skill offers decision guidance to map your questions to the right diagram. However, explicitly stating whether you need a C4 context, sequence, or flowchart diagram ensures the generated code precisely matches your architectural documentation needs.
